Beschreibung

DIC is a carbodiimide used as a coupling reagent for amide and ester formation, widely employed in peptide synthesis in presence of additives such as HOBt or HOAt to supress racemisation. Being a liquid, DIC is easier to handle than the solid DCC and forms a DCM-soluble urea by-product, while DCC generates a urea by-product insoluble in most organic solvents. Since the presence of insoluble urea is reportedly problematic in solid-phase peptide synthesis, for this application DIC is more suitable than DCC. A possible side-reaction with DIC and carbodiimides in general is the formation of an N-acylurea, which can be limited by conducting the reaction in DCM or chloroform at low temperatures, and by adding the amine at last.
